If you think it's hard putting the "Lego Discovery Fire Station" together, how about building and wiring a fully-functioning Mindstorm EV3 robot? To give you a leg up, the Danish toy outfit's joining forces with Autodesk to put together 3D interactive building instructions for the latest generation of Mindstorm mechs. The effects and 3D software firm will use its Inventor Publisher software to create interactive plans that run on iPads, Android devices and web browsers for five different 'bots. That way, you'll be able to actually put on your builder's hat and not just giggle enthusiastically at the final result.
